Description

Technical Field

[0001] This utility model relates to the field of electrical stimulation rehabilitation equipment technology, and in particular to a portable electrical stimulation rehabilitation device. Background Technology

[0002] Electrical stimulation rehabilitation devices are instruments that use electric current to treat the human body, typically used to promote muscle recovery, reduce pain, improve blood circulation, and accelerate the recovery process. They primarily stimulate nerves or muscles with electric current to simulate physiological movement or regulate the nervous system, achieving therapeutic and rehabilitative effects. With current technological advancements, electrical stimulation rehabilitation devices are becoming increasingly portable, making them more convenient for patients to use. However, existing electrical stimulation rehabilitation devices require a connecting cable to connect the device body and the stimulation template. The cable length is fixed, leading to issues of the cable being too long or too short when the user places the stimulation template on different body parts. Adjusting the device body's position is also inconvenient, affecting the ease of use. Furthermore, the contact surface between the stimulation template and the body is a conventional flat surface. When applying electrical stimulation to different areas, the stimulation template cannot conform to the curvature of the skin surface, affecting the tightness of the fit and consequently the therapeutic effect of the electrical stimulation. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a portable electrical stimulation rehabilitation device, which has the advantages of convenient operation and good stimulation effect.

[0004] A portable electrical stimulation rehabilitation device, characterized in that it comprises: a base; a device body detachably mounted on the base; a stimulation module detachably mounted on the base; and a connecting line comprising a first outer tube, a second outer tube, a fixed rod, a rotating plate, a rotating rod, and an electrical wire. The first and second outer tubes are connected by the fixed rod. Two rotating rods are fixed to both sides of the rotating plate. The first and second outer tubes are respectively sleeved on the outside of the two rotating rods, sandwiching the rotating plate in the middle. The first and second outer tubes have through holes. The electrical wire passes through the rotating plate, with one end wound in the forward direction around the rotating rod sleeved in the first outer tube and passing through the through hole in the first outer tube to be electrically connected to the device body. The other end is wound in the reverse direction around the rotating rod sleeved in the second outer tube and passing through the through hole in the second outer tube to be electrically connected to the stimulation module.

[0005] The portable electrostimulation rehabilitation device described in this utility model has a simple and compact structure, making it easy to carry. The structure also allows for the extension and retraction of the power cord by rotating the rotating plate, thereby adjusting the length of the connecting wire according to the body part to be stimulated by the stimulation module. This avoids inconvenience caused by the connecting wire being too long or too short, thus improving the ease of use for patients.

[0006] Furthermore, the two rotating rods are coaxially arranged with the first outer tube, the second outer tube, and the rotating plate. This structure is easy for patients to operate and has a small size that meets the requirements for portability.

[0007] Furthermore, the ends of the first and second outer tubes, away from the rotating plate, narrow into a cone shape and have wire-passing holes. This structure limits the movement of the wire and provides sufficient space between the rotating rod and the outer tubes to accommodate the wire, thus improving the structural compactness.

[0008] Furthermore, the base has a mounting groove whose shape is adapted to the main body of the equipment, and the main body of the equipment is detachably embedded in the mounting groove. This structure allows for quick assembly and disassembly of the main body of the equipment while limiting its position, facilitating maintenance and preventing it from falling off.

[0009] Furthermore, a storage slot is provided on the side of the base, which communicates with the placement slot via a wire groove on the base. The stimulation module is detachably inserted into the storage slot, and the connecting wire is disposed in the wire groove. This structure allows for the storage of the stimulation module, making it convenient for patients to carry.

[0010] Furthermore, the stimulation module includes a connected adhesive ring and a contact piece. An electrode connected to the wire is disposed on one side of the contact piece. The adhesive ring includes an outer ring and an inner ring, with the outer ring fitted over the outer side of the inner ring, forming an adsorption cavity between the outer and inner rings. The adsorption cavity has an opening on the side of the contact piece where the electrode is located. This structure allows the stimulation module to be stably adsorbed onto the patient's skin, without being limited by the curvature of the skin surface, thereby improving the fit and ensuring the stimulation effect.

[0011] Furthermore, the adhesive ring is disposed around the outside of the contact sheet. This structure can further improve adsorption stability.

[0012] Furthermore, an air nozzle is provided on the outer ring, with its outer end connected to an external vacuum device and its inner end connected to the adsorption chamber. This structure ensures that the rubber ring has sufficient adsorption force, guaranteeing the electrostimulation effect.

[0019] Please see Figure 1-4 , Figure 1 This is a structural diagram of the portable electrical stimulation rehabilitation device described in this utility model; Figure 2 This is a structural diagram of the connecting line described in this utility model; Figure 3 This is a diagram showing the internal structure of the connecting wire described in this utility model; Figure 4 This is a structural diagram of the stimulation module described in this utility model.

[0020] This utility model discloses a portable electrostimulation rehabilitation device, including a base 1, a device body 4, a connecting cable 6, and a stimulation module 5. The device body 4 is detachably mounted on the base 1 and is electrically connected to the stimulation module 5 via the connecting cable 6. The stimulation module 5 is designed to fit against the skin to achieve electrostimulation therapy.

[0021] The base 1 can be equipped with hooks, magnets, straps, or other structures at its bottom, allowing it to be mounted and fixed to clothing, limbs, or other objects, thus moving with the patient and improving comfort. The top of the base 1 has a mounting slot 2, the shape of which matches the device body 4, allowing the device body 4 to be embedded in the slot and fit snugly against the base 1, preventing it from falling out. The mounting slot 2 can be fitted with clips or other structures to secure the device body 4 within it. The device body 4 is an electrical stimulation controller, which the patient can control via buttons to supply current to the stimulation module 5.

[0022] A storage slot 3 is provided on the side of the base 1. This storage slot 3 is connected to the placement slot 2 via a wire channel. A stimulation module 5 is inserted into the storage slot 3. The stimulation module 5 can be removed when in use and inserted back into the storage slot 3 when finished, facilitating the carrying of the entire device. The shape of the storage slot 3 is adapted to the stimulation module 5. A power supply can also be installed inside the base 1, and a structure for charging the main body 4 of the device is provided in the placement slot 2. A connecting wire 6 is threaded through the wire channel to prevent the connecting wire 6 from tangling.

[0023] Since the stimulation module 5 will come into contact with skin at different locations, the length of the connecting wire 6 needs to be adjustable according to the position of the stimulation module 5. The connecting wire 6 includes a first outer tube 601, a second outer tube 602, a fixing rod 603, a rotating plate 604, a rotating rod 605, and an electrical wire. The first outer tube 601 and the second outer tube 602 are connected by the fixing rod 603. There are two rotating rods 605, which are coaxially fixed to both sides of the rotating plate 604. When the rotating plate 604 rotates, it drives the rotating rods 605 to rotate together. The first outer tube 601 and the second outer tube 602 are respectively sleeved on the outside of the two rotating rods 605, and the rotating plate 604 is sandwiched in the middle. The ends of the first outer tube 601 and the second outer tube 602 that are close to the rotating plate 604 slide against the rotating plate 604, and the ends that are away from the rotating plate 604 are narrowed into a cone shape and have a wire hole at the end.

[0024] The wire passes through the threading hole of the first outer tube 601 and then winds around the rotating rod 605 fitted inside the first outer tube 601. It then passes through the rotating plate 604 and winds in the opposite direction around the rotating rod 605 fitted inside the second outer tube 602, finally exiting through the threading hole of the second outer tube 602. In use, when the stimulation module 5 is far away, the rotating plate 604 can be rotated, and the rotating rod 605 rotates to release the wound wire; when the stimulation module 5 is close, the rotating plate 604 can be rotated in the opposite direction, and the rotating rod 605 rotates to rewind the wire, thus allowing for flexible control of the wire length. The first outer tube 601 and the second outer tube 602 can be provided with wire grooves extending from the threading hole to the rotating rod 605, allowing the wire to wind around the rotating rod 605 and preventing the wire from coming loose when the rotating rod 605 rotates.

[0025] The stimulation module 5 includes a rubber ring 8 and a contact piece 7. The rubber ring 8 surrounds the contact piece 7, and an electrode is located on one side of the contact piece 7. The electrode is electrically connected to the main body 4 of the device via a connecting wire 6, thereby transmitting current to the user's skin for electrical stimulation and rehabilitation. The rubber ring 8 is made of soft plastic and includes an outer ring and an inner ring. The outer ring is fitted over the inner ring, forming an adsorption cavity between the outer and inner rings. The adsorption cavity has an opening 9 on the side of the contact piece 7 where the electrode is located. During use, the stimulation module 5 can be aligned with the skin of the area requiring electrical stimulation, and then pressed firmly to cause the rubber ring 8 to collapse under pressure, squeezing out the air in the adsorption cavity. This allows the rubber ring 8 to adhere tightly to the skin when released, and keeps the contact piece 7 in close contact with the skin.

[0026] To improve the tightness of adsorption, an air nozzle 10 is also provided on the outer ring. The outer end of the air nozzle 10 is connected to an external vacuum device, and the inner end is connected to the adsorption chamber, so that air in the adsorption chamber can be extracted to maintain the negative pressure state of the adsorption chamber.

[0027] The portable electrostimulation rehabilitation device described in this utility model has a simple and compact structure, and the stimulation module is stably adsorbed, ensuring the effectiveness of electrostimulation. Furthermore, the structure utilizes a rotating plate to extend and retract the power cord, allowing adjustment of the cord length according to the body part to be stimulated by the module. This avoids inconvenience caused by excessively long or short cords, thereby improving ease of use for patients.
